Abstract (en)

An image display apparatus is provided for performing image display by dividing one frame period into two sub-frame periods (± and ²), determining a gradation level of each of the sub-frame periods in accordance with a comparison between a gradation level of an input image signal and a threshold level and supplying an image signal having the determined gradation level to an image display section. In a particular aspect, when the gradation level of the input image signal is equal to or less than the threshold level, the display control section supplies an image signal of a gradation level which is increased or decreased in accordance with the gradation level of the input image signal in the sub-frame period ±, and an image signal of a relatively smallest gradation level or an image signal of a gradation level lower than a prescribed value in the sub-frame period ²; and when the gradation level of the input image signal is greater than the threshold level, the display control section supplies an image signal of a relatively largest gradation level or an image signal of a gradation level greater than the proscribed value in the sub-frame period ±, and an image signal of a gradation level which is increased or decreased by the gradation level of the input image signal in the sub-frame period ².
